<h2>Answer:</h2>

The statement which is true about these rectangles is:

The dilation is an enlargement.

<h2>Step-by-step explanation:</h2>

<u>Dilation Transformation--</u>

It is the translation which changes the size of the original figure.

The shape of the figure is conserved.

Also, in dilation either the size increases (i.e. the figure enlarges) or it decreases( i.e. the figure reduces).

Also, in a polygon if there is a dilation then there is a scalar multiplication in each of the sides of the polygon.

If the scalar multiple is greater than 1 then there is a enlargement.

and if the scalar multiple is less than 1 but greater than 0 then there is a reduction.

Here we see that each of the sides of the original figure is multiplied by "1.5" to obtain a larger rectangle.

This means that the dilation is a enlargement.

( since the scalar is strictly greater than one )

Roes bushes cost $5 and tomato plant cost $2. Write an expression that represent the show the total cost for any number of rose

Anna [14]

<em><u>Expression that represent the show the total cost for any number of rose bushes and tomato plant is:</u></em>

$Total\ cost = 5x + 2y$

<em><u>Solution:</u></em>

Let "x" be the number of roses bush

Let "y" be the number of tomato plant

Cost of 1 rose bush = $ 5

Cost of 1 tomato plant = $ 2

To find: Expression that represent the show the total cost for any number of rose bushes and tomato plant

Total cost = number of roses bush x Cost of 1 rose bush + number of tomato plant x Cost of 1 tomato plant

$Total\ cost = x \times 5 + y \times 2\\\\Total\ cost = 5x + 2y$

Thus the expression is found where, x and y are the number of rose bush and tomoato plant bought respectively

Find the sum of the first 11 terms of the sequence -7,-4,-1, 2 ...

lawyer [7]

Answer:

A The sum of the first 11 terms is 88

Step-by-step explanation:

Since -4 - (-7) = -1 - (-4) = 2 - (-1) = 3

Your sequence is an arithmetic sequence with a common difference of 3.

The formula for the sum of an arithmetic sequence is

$S = \frac{n(a_{1} + a_{n}) }{2}$ where $a_{1} = the first term, a_{n} = the last term, n = the number of terms to be added, and S = the sum$

In your case $a_{1} = -7$ , n = 11 and $a_{n} = a_{11}$

We know everything except the eleventh term.

So, we need to find the eleventh term or $a_{11}$ = $a_{1}$ + (n - 1)d

= -7 + (11 - 1)3

= -7 + 30 = 23

Now, S = $\frac{11(-7 + 23)}{2} = \frac{11(16)}{2} = 88$

The sum of the first 11 terms is 88

What is the solution to this equation? 4x+x-15+3-8=13

deff fn [24]

Answer:

x = 33/5

Step-by-step explanation:

4x+x-15+3-8=13

Combine like terms

5x -20 = 13

Add 20 to each side

5x-20+20 = 13+20

5x =33

Divide by 5

5x/5 = 33/5

x = 33/5
